Three-body abrasion wear resistance of TiC-reinforced low-alloy abrasion-resistant martensitic steel under dry and wet sand conditions

Effect of (Ti, Mo)_xC Particle Size on Wear Performance of High Titanium Abrasion-resistant Steel

“…30) In addition, the comparison study of the abrasive resistance of (Ti, Mo) x C-reinforced steels under dry and wet sand conditions was reported in our previous research. 31) The above results indicated that TiC particles were beneficial in improving the wear resistance of the steel, and the wear resistance was influenced by the size of the particles. However, when the size of the particles changed, the composition or hardness of the experimental steel also changed.…”

“…The experiment was conducted at room temperature using a wet sand/rubber wheel wear-testing machine (model MLS-225), which is the same one that we had used in previous study. 31) A modified ASTM standard test method G105 was used. 38) The test parameters were as follows: the load acting against the specimen was 170 N, the rotational speed was 250 rpm, the hardness of the rubber wheel was 60 Shore A hardness, the diameter of the rubber wheel was 178 mm, the sliding distance was 1 118 m, and the abrasive slurry used in the test consisted of a mixture of 0.94 kg of deionized water and 1.50 kg of quartz sand with sizes in the range of 212-300 μm.…”

“…The hardness is only one factor that influences the abrasion resistance of (Ti, Mo) x C-reinforced steel, the size, the volume fraction and the specie of particle also can influence the abrasive resistance. The wear resistance of a series of (Ti, Mo) x C-reinforced steels with different hardness under wet sand conditions 31) is shown in Fig. 9.…”

Microstructure, Mechanical Properties and Wear Resistance of Low Alloy Abrasion Resistant Martensitic Steel Reinforced with TiC Particles

“…[20][21][22] Thus the concept of MMCs was introduced into low-alloy abrasion-resistant steel, the super abrasion-resistant steel reinforced with self-generated TiC particles was developed through the traditional melting and casting technology. [23][24][25] And the three-body abrasion wear resistance of super abrasion-resistant steels were improved to 1.8 times that of the conventional low-alloy abrasion-resistant steels under same hardness. The micron-sized TiC particles can resist micro-cutting and protect matrix from wear, but the role of nano-sized TiC precipitation remains to be studied.…”

“…The commercial conventional low alloy abrasion resistant steel NM500 with Vickers hardness of 540 was selected as contrast steel, whose composition in weight percentage is 0.28C, 0.31Si, 1.0Mn, 0.013Ti, 0.30Mo and balance Fe. 25) The experimental process is performed according to ASTM standard test method G65 Procedure B. 27) The experiments were carried out at room temperature, and each test of three plates were conducted three times and data were treated using statistical analysis.…”
